By adopting the technology scheme, the dormitory electrical safety can be guaranteed, factors of causing large electrical network branch current can be eliminated, the electricity can be automatically supplied for dormitories, and a large amount of manpower and material resource costs can be saved.
Description
Technical field
The utility model relates to a kind of electric control system of using, particularly a kind of school dormitory Electrical Safety control system.
Background technology
The student in university and some lodging system middle schools generally is the dormitory, accommodates more than hundreds of people in the dormitory.Some student uses powerful devices such as immersion heater, electromagnetic oven, electric water-heating cup in dormitory, the use of these powerful devices can cause the supply load of supply line excessive, might also can cause circuit on fire, not only can cause certain property loss, also can cause great threat simultaneously student's personal safety to school establishment.
At present, school all bans use of for these powerful devices, but the generation that can't stop this phenomenon.The administrative staff of school dormitory adopt the mode of dormitory inspection or seeking to check these powerful devices, and the student conceals these powerful devices through regular meeting, make the dormitory management personnel be difficult to find these forbidding powerful devices.
Some school dormitory adopts the pattern of fuse, the branch road electrical network that is each dormitory installs a fuse additional, when can cause electric current excessive (overload) when using powerful device, blown fuse just needs the maintenance personal of specialty to change fuse to the doorstep this moment.The students' dormitory needed time of waiting for longer before changing fuse like this, and needed the personnel of school's configuration specialty to go up dormitory to change, can cause the waste of manpower and material resources.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence; a kind of control system of electric safety in dormitory is provided; can when using the powerful device of forbidding, the students' dormitory cut off supply line automatically; to protect not excess load of supply line, avoid issuable disaster hidden-trouble.
The technical solution adopted in the utility model is such::
A kind of school dormitory Electrical Safety control system, described system comprises current monitoring transducer, electric-controlled switch, single-chip microcomputer, timer, current monitoring transducer and electric-controlled switch are connected on respectively on the grid branch of each dormitory, the monitor signal output port of current monitoring transducer is electrically connected with an input port of single-chip microcomputer, a control output end mouth of single-chip microcomputer is electrically connected with the control port of electric-controlled switch, and described timer is connected with an input/output end port of single-chip microcomputer.
The current monitoring sensor acquisition is by leading to the electric current on the grid branch of dormitory, the current value of gathering is delivered to single-chip microcomputer, single-chip microcomputer with current threshold default in the current value that receives and the single-chip microcomputer relatively, if the current value that receives is less than or equal to default current threshold, then do not do other responses; When the current value that receives during greater than default current value, then single-chip microcomputer sends a cut-off signal by its control output end mouth, the control electric-controlled switch disconnects grid branch, controlling timer simultaneously picks up counting, when preset time t was arrived in the timer timing, Single-chip Controlling electric-controlled switch closure was to connect grid branch.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: when certain dormitory power consumption is excessive, control system can be cut off the power supply grid branch road of this dormitory automatically, make its outage, and the outage certain hour later on automatically for this dormitory powers on, can realize automatic control, therefore the utility model not only can reach the purpose of school dormitory's safety utilization of electric power, and cost can also use manpower and material resources sparingly.
Description of drawings
Fig. 1 is a kind of students' dormitory of the utility model Electrical Safety control system schematic diagram.
Mark among the figure: 11,12 is grid branch; 21,22 is the current monitoring transducer; 31,32 is electric-controlled switch; 41,42 is single-chip microcomputer; 51,52 is timer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of school dormitory Electrical Safety control system, described system comprises current monitoring transducer (21,22), electric-controlled switch (31,32), single-chip microcomputer (41,42), timer (51,52), current monitoring transducer (21,22) and electric-controlled switch (31,32) be connected on the grid branch (11,12) towards each dormitory current monitoring transducer (21 respectively, 22) monitor signal output port and single-chip microcomputer (41,42) input port is electrically connected, control output end mouth of single-chip microcomputer (41,42) and electric-controlled switch (31,32) control port is electrically connected, described timer (51,52) connects with an input/output end port of single-chip microcomputer (41,42).
Present single-chip microcomputer generally all has certain memory space, and default current threshold is I ' in single-chip microcomputer (41,42); Timer (51,52) is preset a time threshold t '.Current monitoring transducer (21,22) and electric-controlled switch (31,32) all be the grid branch (11 that is connected on towards dormitory, 12), current monitoring transducer (21,22) be mainly used in acquisition stream and cross grid branch (11,12) current value I, the monitor signal output port of current monitoring transducer (21,22) is sent to single-chip microcomputer (41 by lead with current value T, 42) input port, single-chip microcomputer (41,42) compares with the current threshold I ' that presets after obtaining current value I, if I≤I ', then single-chip microcomputer (41,42) is not done any control action; When I＞I ', single-chip microcomputer (41,42) sends the cut-off switch instruction by the control output end mouth to electric-controlled switch (31,32), and starts timer (51,52) simultaneously and pick up counting; When timer (51,52) timing is to threshold value t ' time time, single-chip microcomputer (41,42) pass through the control output end mouth to electric-controlled switch (31,32) send the Closing Switch instruction, gather once more this moment grid branch (11,12) electric current and with single-chip microcomputer (41,42) in default current threshold I ' compare, if the current value of gathering is less than or equal to current threshold I ', illustrate that then this grid branch (11,12) eliminated powerful load, Closing Switch is this dormitory power supply, otherwise single-chip microcomputer (41,42) control electric-controlled switch (31,32) and start timer (51,52) from newly picking up counting.
The utility model can disconnect this grid branch when the grid branch circuit is excessive, to eliminate the excessive potential hazard that causes of electric current, after certain hour, can detect the factor that causes the grid branch electric current excessive of whether having eliminated, if eliminated then this grid branch of auto-closing, otherwise disconnect this grid branch and start the timer reclocking.The technical solution of the utility model not only can guarantee the dormitory Electrical Safety, can also cause the excessive factor of grid branch electric current to power on automatically for dormitory later on having eliminated, and can save the lot of manpower and material resources cost.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
